Kaylem and I collected the Gem tang this evening and it is now in the QT system with the rest, but as you can see there is a egg crate divider separating the Scopas and the Gem. This will stay for a while and I will monitor the behavior. If I feel they will tolerate each other in such a small space (unlikely) then I will remove it. I have also attached a video of the fish in the shop display tank which they sent to me yesterday. It's a spectacular specimen and I'm really happy.
